Buying Guide for the Best 20 Inch Gas Chainsaw

Choosing the right 20-inch gas chainsaw involves understanding your specific needs and matching them with the right features. A 20-inch chainsaw is typically used for medium to heavy-duty tasks such as cutting firewood, felling trees, and storm cleanup. It's important to consider the power, weight, safety features, and ease of use to ensure you get the best fit for your requirements. Here are the key specifications to consider when selecting a 20-inch gas chainsaw.
Engine PowerEngine power, measured in cubic centimeters (cc), determines the chainsaw's cutting ability and efficiency. Higher cc means more power, which is essential for cutting through thick wood. For a 20-inch chainsaw, engine power typically ranges from 45cc to 60cc. If you plan to use the chainsaw for heavy-duty tasks like felling large trees, opt for a higher cc. For lighter tasks, a lower cc will suffice and be easier to handle.
WeightThe weight of the chainsaw affects how long you can use it comfortably. Heavier chainsaws can be more tiring to use, especially for extended periods. Chainsaws in this category usually weigh between 10 to 15 pounds. If you need to use the chainsaw for long durations or have less upper body strength, choose a lighter model. For occasional use or if you have more strength, a heavier model might be acceptable.
Safety FeaturesSafety features are crucial to prevent accidents and injuries. Look for chainsaws with features like chain brakes, anti-vibration systems, and low kickback chains. Chain brakes stop the chain instantly if a kickback occurs, while anti-vibration systems reduce fatigue and improve control. Low kickback chains are designed to minimize the risk of kickback. Prioritize models with comprehensive safety features, especially if you are a less experienced user.
Ease of MaintenanceRegular maintenance is essential to keep your chainsaw in good working condition. Features like tool-less chain tensioning, easy access to the air filter, and automatic oiling systems can make maintenance simpler and quicker. If you prefer minimal maintenance hassle, look for models with these user-friendly features. This will ensure your chainsaw remains efficient and prolong its lifespan.
Fuel EfficiencyFuel efficiency determines how long the chainsaw can run on a full tank of gas. More fuel-efficient models will save you money and reduce the frequency of refueling. Look for chainsaws with advanced engine technologies that offer better fuel consumption. If you plan to use the chainsaw for extended periods, a more fuel-efficient model will be beneficial.
Vibration LevelsHigh vibration levels can lead to user fatigue and discomfort, especially during prolonged use. Chainsaws with lower vibration levels are more comfortable to use and reduce the risk of hand-arm vibration syndrome. Look for models with anti-vibration technology or dampening systems. If you plan to use the chainsaw frequently or for long periods, prioritize models with lower vibration levels.
Starting MechanismThe starting mechanism affects how easily you can start the chainsaw. Some models come with easy-start systems that require less effort to pull the starter cord. This is particularly useful if you have less upper body strength or if you need to start the chainsaw frequently. If ease of starting is important to you, look for models with features like spring-assisted starting or decompression valves.
